Verdict
The clearest difference is rating: CJ ONE at 3.5 against GOODDUCK's 2.3. CJ ONE also leads on ratings volume (37 vs 3) and device support (3 vs 1). GOODDUCK's advantage is ads (none vs shown) and review sentiment (98% vs 71%). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CJ ONE holds the better App Store score, 3.5 against 2.3. That said, the two scores are not equally well evidenced: CJ ONE has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 71% of CJ ONE's written reviews are positive against 98% of GOODDUCK's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly monthly. Both last shipped on October 24, 2026.
